METAL BOX.

270; all whom it may concern:

Be it knownthat I, GOTTIJEB K an-K, a

.citizen of '"the United States, residing at '1 efiaI ce, 1n the county of Defiance and a State of Ohio, have "invented certain new and useful Improvements in Metal Boxes, of which the following is a specification,

reference being-had therein to the accompanying drawings.

' My invention relates to improvements in sheet metal boxes, relating more particularly to the corner structure of the bottom of the, box, this application being a division of'the application filed by me July 13', 1907,,

Serial No. 383,642.

Theobjects of my invention are to provide a construction of this character in which-the corner of the box and the portion of the bottom adjacent thereto are con nected in .a manner to mutually support each other, at the same time acting to reinforce the parts and stiffen themfthereby enabling a sheet metal box ,to be formed of relatively. light material but capable of withstanding the hardest uses, the box be- .ing capable of use for shipping purposes,

etci; additionally an object of the invention is :to providea structure which can be made of standard blanks readily assembled, and which, when assembled, provides a box of maximum efliciency.

To these and other ends, the nature of which :will be readily understood as the invention is hereinafter disclosed, my. inventionconsists in the improved construction andcombination of parts, hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

this application filed. January 2/2,

the invention as appl1ed. F-1g-. 1s a detail of one of the bottom relnforcing strips in blank form.

As. disclosedin the parent application, the Q box-is formed with side and indicated respectively at 1' and tions. being folded upon each other to provide substantial corner seams 3; the top edges ofv the sections are also headed to inclose-a reinforcingelement 4- The bottom end sections, 2, these secis indicated at 5., being formed with open ings 6. The outer: edges of the bottom are connected to the side and end sections by being crimped thereto.

7 and 7? designate reinforcing strips which are located below the bottom, these.

strips being adapted to form a portion of the crimp which connects the side and end sectionswith the bottom, this construction being shown -more particularly in Fig. 3. The crimped portion comprising the three parts, the bottom, the reinforcing strip and the side or end sections as the case may be,

acts to provide a "supporting flange 8, as,

exhibited in Fig. 3. The construction serves to' provide not only. an eificient binding for the parts, but, by reason of the particular form of the parts so connected, acts to prevent distortion of the edge of the box along the bottom without requiring the use of a predetermined forms even under violent.

usage. The reinforcing strips have the inner edges of their. intermediate portions adapted, ii -connection with a reinforcing element 9, to form a bead or flange 10, the inner. edges of the strips being rolled over the element, so that the latter acts to prevent distortion of the strips and therefore addi- As'showmmore particularly in Figs.
